The purpose of this study was to examine the relationship between lingual muscular strength (LMS) and articulatory proficiency in 45 normal and 45 lisping speakers utilizing a Lingual Force Scale designed specifically for this investigation. Results revealed that lispers exhibited significantly reduced LMS as compared to their matched controls. No significant differences in LMS between males and females with lisped speech, or between normal speaking males and females were found to exist at 5 age levels. Significant positive correlations were noted between age and LMS in both groups of subjects. In light of these findings, it might be suggested that lisping should not be viewed always as a purely functional disorder of the speech musculature.
本研究的目的是利用专门为此项调查设计的舌力量表，检验45名正常发音者和45名口齿不清者的舌肌力量（LMS）与发音熟练度之间的关系。结果显示，与匹配的对照组相比，口齿不清者的LMS显著降低。在5个年龄组中，口齿不清的男性和女性之间，以及正常发音的男性和女性之间，LMS均未发现显著差异。两组受试者的年龄与LMS之间均存在显著的正相关。鉴于这些发现，可能有人会提出，口齿不清不应总是被视为一种纯粹的言语肌肉功能障碍。
